Abstract

An inserter (100) for subcutaneous insertion of multiple transcutaneous parts (212, 222), the multiple transcutaneous parts at least comprising: —a first transcutaneous part (212) comprising a first body (214) from where a first subcutaneous part (216) extends, and —a second transcutaneous part (222) comprising a second body (224) from where a second subcutaneous part (226) extends, wherein the inserter comprises: —support means for guiding the multiple transcutaneous parts during insertion of the multiple transcutaneous parts, and —activation means for activating the inserter, whereby simultaneously insertion of the multiple transcutaneous parts subcutaneously in the patient'"'"'s skin is initiated.

Claims

1. An inserter (100) for subcutaneous insertion of multiple transcutaneous parts (212, 222), the multiple transcutaneous parts (212, 222) at least comprising:

a first transcutaneous part (212) comprising a first body (214) from where a first subcutaneous part (216) extends, and

a second transcutaneous part (222) comprising a second body (224) from where a second subcutaneous part (226) extends,

wherein the inserter comprises;

support means for guiding the multiple transcutaneous parts during insertion of the multiple transcutaneous parts, and

activation means for activating the inserter, whereby simultaneously insertion of the multiple transcutaneous parts subcutaneously in the patient'"'"'s skin is initiated.

2. An inserter according to claim 1, wherein the support means comprises a functional first part (600) with a proximal first part (604) supporting the multiple transcutaneous parts (212, 222) in a pre-use position.

3. An inserter according to claim 2, wherein the support means further comprises multiple introducer needles comprising at least a first introducer needle (218) supporting the first subcutaneous part in the pre-use position and a second introducer needle (228) supporting the second subcutaneous part in the pre-use position.

4. An inserter according to claim 3, wherein the first introducer needle (218) is extending through, partly surrounding or fully surrounding the first subcutaneous part in the pre-use position and the second introducer needle (228) is extending through, partly surrounding or fully surrounding the second subcutaneous part in the pre-use position.

5. An inserter according to any of the preceding claims, wherein the first transcutaneous part (212) and/or the second transcutaneous part (222) is a sensor.

6. An inserter according to any of the preceding claims, wherein the first transcutaneous part (212) and/or the second transcutaneous part (222) is a cannula part.

7. An inserter according to any of the preceding claims, wherein the inserter comprises a cover (104, 106) and the activation means (108) are activation points positioned on the cover.

8. An inserter according to claim 7, wherein the activation of the inserter is initiated by applying a pressure to activation points in a direction substantially perpendicular to the direction of insertion.

9. An inserter according to any of the preceding claims, wherein the inserter further comprises driving means, wherein upon activation of the inserter, the driving means drives the inserter from the pre-use position to an inserted position, wherein the multiple transcutaneous parts (212, 222) are inserted in the patient'"'"'s skin in the inserted position.

10. An inserter according to claim 9, wherein the driving means is a primary spring (230) extending in the direction of insertion.

11. An inserter according to claim 10, wherein the primary spring (230) upon activation of the inserter translates from a loaded position to an unloaded position, thereby promoting the multiple transcutaneous parts (212, 222) from the pre-use position to the inserted position, where the multiple transcutaneous parts (212, 222) are inserted subcutaneously in the patient'"'"'s skin.

12. An inserter according to claim 11, wherein the inserter further comprises a first function part (600) having a proximal first part (604) with a distal surface (603), the distal surface (603) supporting the primary spring (230), wherein the primary spring (232) pushes the first functional part (600) from a first position to a second position as the primary spring (232) translates from the loaded position to the unloaded position.

13. An inserter according to claim 12, wherein the inserter further comprises a release ring (500), which in the first position engages with the first functional part (600) securing it in the pre-use position and in the second position no longer engages with the functional first part (600), whereby the primary spring translates from the loaded position to the unloaded position.

14. An inserter according to any of the preceding claims, wherein the inserter after insertion of the transcutaneous part (212, 222) automatically translates to a retracted position where the inserter is separated from the multiple transcutaneous parts (212, 222).

15. An inserter according to claim 14, wherein the translation to the retracted position is promoted by retraction means.

16. An inserter according to claim 15, wherein the retraction means comprises a secondary spring (232) extending in the direction of insertion.

17. An inserter according to claim 16, wherein the inserter further comprises a functional second part (700) supporting the secondary spring, wherein the secondary spring (232) after activation of the inserter and insertion of the multiple transcutaneous parts (212, 222) translates from a loaded position to an unloaded position, thereby promoting the functional second part (700) from the inserted position to a retracted the position, whereby the inserter is separated from the multiple transcutaneous parts (212, 222).

18. An inserter according to claim 16 or 17, wherein the distal surface of the proximal first part supports the secondary spring (232).

19. An inserter according to claim 17 or 18, wherein the multiple introducer needles are attached unreleasably to the functional second part (700).
